STUMP-EULLER.

T all whom it may concern:

Be it known that I, CLYDE F. Bonus, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stump- Pullers; and I do hereby declarethat the following is a full, clear, and exact description of the same, reference being had'to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

A large number of stump pulling devices have been constructed which merely consist of a multiplying gear adapted to be in terposed between the stump to be pulled and a suitable anchorage, whereby a subd to the acting to tear the stump from the ground, due to the leverage afforded by the distance between the gripping cable applied around the stump and the roots of the same. It is obvious that in such a construction great difficulty is encountered in pulling very short stumps for the reason that the leverage is a function of the height of the stump, and consequently a horizontal stump ullin ear mav sometimes rove inade- P z: a: t

quate for the purpose. I

This invention relates to means for pulling stumps wherein the force applied is directed substantially in line and in a vertical direction, and the efiectiveness of the device is unaffected by the length of the stump. 7

It is an object of this invention to provide a power driven mechanism adapted to travel from place to place, and equipped with devices such that the powerplant maybe used for pulling stumps and other purposes.

It is also an object of this invention to provide a tripod frame adapted to be centered over a stump and adjustably connected to a power driven mechanism.

It i's'also an object of this invention to rovide a device having a power plant, and a stump pulling tripod frame, wherein the lant ma be utilized to adjust the tripod frame, pull a stump, or drive the mechanism from placeto'place.

It is also an object of this invention to "provide a self propelling vehicle having a stump pulling member adjustably and fleXibly connected thereto. '1

"It is also an object of this invention to driven adjustable tripod frame, multiplying gears Specification of Letters Patent.

of various ratios, all driven from a unit power plant.

It is furthermore an object of this invention to provide a device having a tripod frame pivotally connected thereto adapted for adjustment.

It is'finally an ob ect of this invention to provide a device capable of a number of simultaneous operations, any one of or combination of which may be effected simultaneously.

The invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

In the drawings: Figure 1 is a top plan view of a device with the tripod lowered to pulling position. Fig. 2 is a side elevation thereof with one leg of the tripod frame broken away, and showing one position of the frame in dotted lines during the elevation thereof from operating position. Fig. 3 is an end elevation of a device connecte and in operative position to pull a stump, and with the tripod illustrated fragmentarily in dotted lines in position out of use. Fig. i is a fragmentaryside elevation of a modification of the adjusting means or the tripod. Fig. 5 is a fragmentary end elevation thereof. Fig. 6 is a fragmentary end elevation of another modification of the connection existing between the tripod and the self propelled power plant.

As shown in the drawings, the power plant is mounted upon a main frame 1, having driving wheels 2, and steering wheels 3, the latter of which are operated by means of a chain 4:, wound around a suitable drum driven by the worm wheel 5, which is in turn driven by a worm 6, connected to a steering wheel 7. A running board 8, is provided along one side of the frame to accommodate the operator. The power plant consists of a bo'ler 9, and steam engine 10, which drives the longitudinal crank shaft 11, for various purposes hereinafter described. Of course any other suitable source of power such as a gasolene or electric motor may be used. Bevel pinions 12, and 13, are secured upon the crank shaft, the former rigidly, and the latter loosely upon the same, said pinions serving to drive respectively the large'bevel gears 1i, and 15. Aclutch 15 is provided to connect the loose gear 13, with the crank shaft when desired. The bevel gear 1a, is secured upon the shaft 16, which is journaled in suitable bearings upon the main frame 1. Loosely engaged the short extremities of thelevers connected are gears 17, and 18, of V by meansoflinks 50, to said shoe 46. A

' retracted by means of the ruin- 34, andthe are, also plvotedon said-main frame with ped thereover,

tripod moves about the pivot point 68, into an elevated position out of use. It is obvioils that in these constructions inequalities in the ground, as well as the strain induced in the tripod due to the pulling of a stump, will not be transmitted to the main frame through the attaching means between the tripod frame and the main frame, owing to the fact that no rigid connection exists therebetween. l

The operation is as follows: When it is desired to pull a stump, the machine is placed beside the same and the tripod dropwith the outer shoe 47, thereof and inner shoe 4:6, resting upon the ground. The cable 62, is then engaged about the stump and the clutches 19, and 22, each thrown into engagement thereby causing the drum 21 to be driven from the engine, and winding the cable 59, thereupon. Owing to the large multiplication of power efiected through the tackle means, the stump is easily pulled from the ground. It is readily apparent that with the tripod properly centered above the stump, the entire reaction due to pulling of the stump from the ground is transmitted through the spars. to more securely anchor the tripod in position, and no strain other than that due to the winding of the cable 59, upon the drum 21, whichis a relatively small quantity, due to the multiplication of power, is imposed upon the main frame. This is an important feature of the invention as the power plant frame or main frame may be relatively light, though strong enough to withstand the stress brought into play when moving from place to place with the tripod frame carried entirely thereon. Generally in other-similar constructions, a crane arrangement mounted directly and entirely upon the main frame has been used but in such constructions all the stresses must be borne by the main frame thus necessitating a heavy structure difiicult of movement from place to place.

I am aware that details of construction may be varied through a wide range without departing from the principles of this invention. I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described, a frame, a power plant thereon, a tripod mounted at one side of said frame, tackle adapted to be driven by said power plant to elevate said tripod into a position out of use, booms connected to the lower end at one side of said tripod and at their other ends to said frame to swingingly support the tripod on thelframe with the aid of said tackle, block and tackle mounted in said tripod, a sheave at the lower end of the tri- Gopies of this patent may be obtained for pod, and a Windlass on the frame adapted to receive the end of said last mentioned tackle permitting a stump to be withdrawn from the ground in such manner that the reaction of pull and the tenslon on the tackle is transmitted through the tripod to the ground relieving the frame of stress.
